Wise-DRAWING APPARATUS.

PECIFICATION forming part of Letters Patent No. 309,688, dated December23, 1884-. Application filed September iii, 1884. (No model.) Patentcdin France February 18, 1884, No. 160,359.

T0 call 107mm it may con'cern:

Be it known that I, J EAN Manna BulssoN, a citizen of the FrenchRepublic, residing at Belmont, in said French Republic, have inventedcertain new and useful Improvements in Methodsof and Machines forDrawing Vire, for Which I have obtained Letters Patent in France, No.160,389, under date of February 18, 188-l,) of which the following is aspecification.

In the manufacture of Wire, and more especially Wire from ductile metalssuch as soft iron, gold, silver, copper, &c. -it has been the custom toreduce the wire to the desired size by passing the same through a seriesof drawplates, or through a draw-plate having a series of graduatedreducing-eyes, the reduction beng effeeted by successive Operations of'drawing, reeling, pickling, and lubricating.

The object of this invention is to diminish the labor connected withthis mode of drawing Wire by red ucing the same at a single operation,the Wire being drawn from the coarser i to the finishing platesuccessively through all the intermediate plates.

The invention consists, essentially, in mechanisms and in combination ofmechanisms for reducing Wire to the proper thickness by a singleoperation by passing said Wire through a series of draw-plates,maintaining the Wire at the proper tension, and cooling the same on itspassage from one draw-plate to the other, substantially as hereinafterdescribed.

In the accompanying drawings, Ihave illustrated in Figure l by aperspective so much of a machine for drawing Wire according to myprocess as will be necessary for the thorongh understanding ofthe'invention. Fig. 2 is an end elevation, showing the driving mechauismonly.

The operative devices of the machine are supported by a 'suitable frame,in Which said devices operate, and in which they have their bearings.,The frame A, as shown, is composed of a table or platform, a, supportedon uprights a', connected together by means of longitudinal girts (L2.At the rear end of the table in suitable bearings is mounted the maindriving-shaft Z), driven from a suitable prime motor, and carrying abelt-pullcy, B, belted.

to a pulley, C2, on a shaft, c, and a sprocketwheel, B', connected bychain with a like wheel, C3, on said shaft c. The latter shaft alsocarries a second belt pulley, Of, and sprocket-wheel C'.

Between the pulleys Olz C* on s'haft c is mounted a conical pulley, C,belted with a like pulley, D, mounted on a shaft, (Z, near the platformof the machine, upon the belt d' of Which pulley bears a brake-shoe, E,adjustable along the periphery of the said cone-pulley D in a slot, of abrake-lever, E', pivoted. to the platform a of the frame A, or slidingin a guideplate, 6/, as shown. The sproeket-wheel O2 is connected bychain 02 With a like wheel, F2, on a shaft, f, that also carries acone-pulley, F.

Between the cone-pulley F and the sproeket-wheel F2 on shaft f ismounted a second sprocket-wheel, F, of smaller diameter than thesprocket-wheel F2, connected by chain to a sprocket-wheel, G2, on shaftg, which shaft also carries a cene-pulley, G, and between the eonepulley and the sprocket wheel G2 is mounted a sprocket-Wheel, G', ofsmaller diameter than the sprocket-wheel G2..

It Will be observed that the gearing shown and above described is soarranged as to drive the parts driven therefrom and herein described ata uniform speed, and that the speed of said parts relatively to andindependently of each other may be varied by means of the cone-pulleys CF G, so that the speed of said parts may be gradually increased from thefeed end to the delivery end of the machine. The eone-pulleys C F G arebelted With like pulleys, H, I, and K, mounted on top or platform of themachine in suitable bearings. The shaft or journal IL of the cone-pulleyH carries the spool H/ from which the Wire is fed, the journal of thecone-pulley I carries a guide or speed pulley, 1', and that of thepulley K a guide or speed pulley, K'.

On suitable standards are mounted disks,

or, preferably, drums M, M', M2, &c., over which the Wire passes and iscooled, and said drums may be kept cool by a circulation of cold Wateror other heat-abstractiug medium fed thereto through one of their hollowstandards and one of the hollow trunnions of the drums, said mediumescaping from the drum IOO through the other hollow standard and trun-vnion in a well-known manner.

N N' are tension-pulleys mounted on levers a a', over which pulleys theWire is passed, and by which it is kept at the proper tension. Saidlevers a o a' project through suitable openings in the platform andextend some distance below thesame, said levers being pivoted insuitable bearings. (Not shown.)

S S' S2 are hangers depending from the platform of the frame. They carryat their lower ends pulleys 8 8' 81, respectively, over which passes achain, wire, or cord, a. One end of the cord W is attached to an arm,0', projecting from a rod, O, that is stepped in a bearing, 02, at thefoot of the frame, said rod O carrying at its upper end an arm, o, thathas a locking tooth, O', adapted to engage the notches or teeth of aSector-plate, O2. The wire, chain, or cord W, attached to arm o', afterpassing around the pulley s on hangcr S, passes around a like pulley,8', on hanger S', the opposite end of said cord being secured to thelower end of the rod a'. or to an arm projecting therefrom. A cord thathas aweight, p', attached thereto serves to hold the cord a at thetension at which it has been adj usted.

It is obvious that if any one of the tensionadjusting rods O is rotatedin a given direction the arm 0 will either draw upon the cord a* orslacken the same, thus moving the levcr in one or the other direction totighten or slaeken the wire VV, that 'passes around its tension-pulleyat the upper end thereofl' Q Q' Q2 are the draw-plates, the draw-eyes ofwhich are succcssively of smaller diameter.

R R' are belt-shifters for shifting the belts on the cone-pulleys O F GH I K to regulate the speed of the spool and the guide-pullcys II' 1/K', as will be readily understood. The wire WT, wound on spool H',passes through the first draw-plate Q, thence over and aroundtensionpulley N,back again toward the spool,and over and around thecooling-drum M. From the lattersdrum said wire XV passes around theguide or feed pullcy I', from the feed pulley the Wire passes throughthe eye of the second draw-plate Q', thence around the tension-pulleyN', back toward the feed-pulley I' over the cooling-drum M'. From thelatter drum the wire passes around feed-pulley K', then through vthethird draw-plate Q2, around another tension-pulley, back towardfeed-pulley K, and around cooling-drum M2 to the next feed-pulley, andso on to and through the finishing or last draw-plate, from which itpasses to a sp ool on which the wire XV, reduced to the desiredthickness, is wound.

I have deemed it sufficient to show in the drawings but threedraw-plates, the spool from which the wire is reeled, three tension andtwo feed-pulleys, and the devices necessary thereto to regulate thetension of the wire NV, in order to illustrate the invention and renderthe same intelligible to those conversant with this branch ofmanufactures. I would, however, have it understood that I do not confinem yself to the number of the elements described, as it is 'obvious thatthey may be multiplied, and in fact, in practice, 'a greater number ofdraw-plates are used, consequently a greater number of feed and tensiondevices.

To those conversant with this branch of inanufactures the advantages ofmy invention will be readily understood, and I mayvstate that, asidefrom the great amount of labor and expense saved and the cleanliness ofthe work, the process of drawing wire has a further ad- Vantage, thatthe wire is not liable to become heated as in the old mode of drawingwire.

Furthermore, the wire being kept at a uniform tension by yieldin gtension devices, is not subjected to any sudden jerks due to anirregularity in the speed of the winding-drum, or liable to any slackdue to the speed of the feeddrum.

The speed at which the wire is drawn through the draw-plates may bevaried according to the nature of the metal. The drawing is effeetedslowly, and consequently without injury to the metal, each draw-platehaving its own feeding devices, the speed of which may be regulated.Finally, awire more pliable is obtained than can be obtained by the oldmethod of working.

Instead of driving the cone-pulleys O F G by sprocket-wheels and Chains,they may be driven by belts or by toothed gearing.

I-Iaving thus described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. In a' wirc-drawing machine, the combination, substantially as hereindescribed, of a series of draw-plates arrangcd successively, and havingreducingeyes of gradually-deereasing diameter fromthe feed toward thedelivery end, feeding devices for feeding the wire to the plates,drawing-pulleys for drawing the wire through .the plates, andtension-pulleys supported from weighted levers to maintain the wire atthe proper and at a yielding tension while passing from one draw-plateto the other, for the purposes specified.
